28.3889 is the example result. DSO converts receivables relative to annual sales into days using a 365-day convention. A balance-sheet snapshot is not the same as invoice-level collection history.
DSO converts receivables relative to annual sales into days using a 365-day convention.
Keeping timing visible in cash decisions
DSO converts receivables relative to annual sales into days using a 365-day convention. A balance-sheet snapshot is not the same as invoice-level collection history. Profit does not state when money reaches the bank. Receivables, supplier payments and inventory can absorb cash while sales remain healthy. A cash comparison needs the payment window and outstanding balance, not only the invoice total.
Source and result record
For dso, retain Accounts receivable, Credit sales together with the output. Record the date of the source values and the unit convention used in the form. That record separates a change in the underlying case from a change in how the information was entered. A saved result without its source values cannot show which assumption produced it.
Example with the supplied inputs
Accounts receivable: 70000; Credit sales: 900000. Result: 28.3889. The values are illustrative.
Compare one changed input
Accounts receivable changes from 70000 to 77000. The result becomes 31.2278. All other inputs remain fixed.
Calculation rule
Result = (([Accounts receivable]) ÷ ([Credit sales])) × 365
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Accounts receivable | 70000 | Use the source quantity represented by accounts receivable. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Credit sales | 900000 | Use the source quantity represented by credit sales. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 28.3889 is the example result. DSO converts receivables relative to annual sales into days using a 365-day convention. A balance-sheet snapshot is not the same as invoice-level collection history. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Accounts receivable, Credit sales. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Accounts receivable on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 28.3889.
Change Accounts receivable from 70000 to 77000 while keeping every other value fixed. The result becomes 31.2278. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
